BOX WALL FOR LOOMS Filed Jan. 28, 1947 Patented Apr. 22, 1952 BOX WALL FOR LOOMS Harold Hueber, deceased, late of South Dartmouth, Mass., by Barbara O. W. Hoeber and William T.

2 Claims. l

This invention relates to a loom and more particularly to the wall of the shuttle box.

The shuttle box carried by the lay of a loom usually has a back wall which is attached at its inner end to the lay sword and may be adjusted at this end. The back Wall in the Draper loom is cut out so that the back binder extends through this wall of the box and may swing inwardly. The outer portion of the back wall is fxedly mounted to the lay and at this outer end the back binder is pivoted. By this arrangement only the inner end of the back wall of the box may be adjusted and consequently the shuttle may be given a serpentine path by reason of the fact that the outer end of the back binder is not moved correspondingly when adjustment is made at the Vinner end of the back wall. Further, this back wall by reason of its cut out for the back binder is not rigid and may become distorted in its position. It forms an inadequate support for the back binder. If the binder were in the front wall the same would be true.

One of the objects of the invention is to provide a guiding surface for the shuttle above and below the binder so that the shuttle is subject to guidance, in its outward and inward motion. by a. continuous rigid wall.

Another object of this invention is to provide a box Wall which may be adjusted at the outer end oi' the shuttle box.

Another object of the invention is to strengthen the end of the lay.

Another object of this invention is to provide a better mounting for the box binder.

Another object of this invention is to provide a stronger and more rigid attachment for the lay end to the sword.

Another object of the invention is to provide a more rigid mounting for the hinge of the box binder.

Another object of the invention is to provide an improved means of attaching the box wall of the shuttle box to the lay.

Another object of the invention is to provide a means for vertically aligning guiding edges of the box wall of the shuttle box which mount the box binder.

With these and other objects in view. the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a sectional view illustrating a fragmental portion of a loom and illustrating more 11;i;.rticu1ar1y the end of the lay showing the shuttle Fig. 2 is a top plan view of the shuttle box with parts in section;

Fig. 3 is a sectional view on line 3-3 of Fig. 2;

Fig. 4 is a perspective view of the back of the shuttle box;

Fig. 5 is a section on substantially line 5-5 of Fig. 1.

In proceeding with this invention there is provided a rigid box wall for a shuttle box with a slot therein, the wall being of suiiicient thickness so that the slot will provide a surface area sufcient to provide a good support for the box binder which is pivotally mounted in this slot to Work through the wall of the box. This box wall is also mounted so that it will be adjustable at its outer end and also adjustable at its inner end.

Thus, the box wall may be nicely positioned to locate the wall as desired that the shuttle may be guided in a straighter non-rotating path of travel when struck by the picker stick to .drive it out of the box. By reason of the box wall providing substantial masses on both sides of the binder. a very rm and solid pivotal mounting of the box binder is provided and the lay end is better reinforced.

With reference to the drawings, I0 designates a portion of the framework of the loom and II designates the lay swords which mount the lay |2 thereon. A reed I3 is carried by the-lay carrying a cap I4. The protection rod is shown at I5 with an arm I6 extending upwardly therefrom to engage the box binder. The shuttle box is designated generally I6 and as shown in Fig. 2 consists of a front wall Il, a bottom wall I8` (see Fig. 2) held in position by screws I9 and 2U with a front flange 2| and a back flange 22 or abutment extending downwardly on either side of the lay I2. A slot 23 is provided in the lay at the location of the shuttle box for the reception of the picker stick 24 which is encircled by the check strap 25 carried by the check strap bracket 26 which is fastened onto the lay I2. The cushion member 21 is located at the outer end of this slot 23 and the picker 28 is mounted at the upper end of the picker stick for engagement with the shuttle to throw it across the loom.

The back wall of this shuttle box I6 is designated generally 30 and is shown in perspective in Fig. 4. It is a. rigid casting in one piece with its widest portion 3| adapted to engage the upper end of the lay sword I I. Two abutment or lling strips 32 and 33 are provided for engagement with this lay sword while this portion 3| is drawn up against the lay sword by reason of a threaded opening 34 and a headed screw 35 (see Fig. 2) which extends through the lay sword and into 3 this threaded opening 34. The position of this end of the back wall will be governed by the relative location of the surfaces of the abutments 32 and 33 which may be led to provide the proper alignment while the bolt draws these securely against the surface of the lay sword. From the widest portion 3| the box back is narrower as at 35 and also thicker for greater support of the box binder. This portion is slotted as atv 31 -for the reception of the box binder 38 which slot 31 extends throughout the remainder of the length of the back wall and provides portions 39 and 40 in spaced relation which are connected by a bridging vThis flange 42 is mounted on the lay by reason of screws 41 and 48 extending through the openings 43 and 44, and into threaded openings 49 and 50 in the ange 22 which extends downwardly-from the bottom wall i8 of the shuttle box.

These screws will draw this flange andl conse- 4quently the inner end of the back wall inwardly as they are set up. Screws 5| and 52 (see Figs. 3 and 5) extend through the threaded openings 45 and 46 and are provided with check nuts 53 and 54 so as to hold these screws 5I in adjusted position. The inner end 55 of the screw 5| provides an 4abutment as does the inner end 56 of the screw 52 which engage the flange 22 and limit the amount that the outer end of the back wall 30 may be drawn inwardly by the screws 41, 48. By relatively setting up the screws 5| and 52 more or less the vertical alignment of the, back wallv 30 may be provided. By backing these screws out of their openings 45 and 46 and setting up the screws 41, 48 the outer end of thewall .30 may be drawn closer to the front wall, whereas ,lower portions of the back wall is such as to pre- 4vent rotating of the shuttle about its longitudinal axis due to the action of the binder as the shuttle is picked out of the box.

The box binder 38 is provided with a hole adjacent the outer end of the shuttle box to align with holes 55 in the portion 39 and 56 in the portion 40 for the reception of a hinge pin 51 (see Fig. 2) which will extend through the aligned openings to hingedly mount the box binder 38 in the slot 31 in the back wall. This box binder will slide upon the inner lsurface 59 of the lower portion 40 of the box binder which provides a good supporting surface'upon which it may rest. Due to the adjustment of the back wall the box binder will have little or no effect in guiding the shuttle. The box binder acts only as a frictional means and operates the protection system and, if desired, may be used as a subsidiary check for the shuttle and especially to ,hold the shuttle stationary momentarily when ing the outer end of said back wall for adjustment toward and from the front wall, said means .comprising a threaded member threaded into said slotted wall and engaging said abutment.

2. A shuttle box as set forth in claim 1 wherein the second said means comprises a pair of vertically arranged threaded members threaded through said slotted wall and engaging said abutment for adjustment about the horizontal axis or said slotted wall.
